. Distribution of boghead algae in Illinois Basin coal beds. Paleobotany; Torbanite; Algae, Fossil; Coal; Coal; Spores (Botany), Fossil. 50 um Plate 1 The occurrence of Botryococcus in crushed particles of coal. Samples were embedded in epoxy, polished, and examined under an oil immersion lens. All images are magnified about 400x. Pairs A and B and C and D are the same image. Under white light (A and C), Botryococcus appears mottled reddish brown, whereas under blue light excitation (B, D, E, and F) it fluoresces bright yellow. Liptinite macerals associated with Botryococcus include sporinite

Under white light (A and C), Botryococcus appears mottled reddish brown, whereas under blue light excitation (B, D, E, and F) it fluoresces bright yellow. Liptinite macerals associated with Botryococcus include sporinite (dark brown in C and dull yellow in D) and small irregular masses of bituminite (brown in A and faintly brown in B and E). The matrix commonly surrounding Botryococcus is desmocollinite (gray in A and C), a type of vitrinite. In F, the outer edges of the alga masses appear scalloped. *.
